Some of the clamps may be provided with Figure 4: is an end elevation of a further extensions 9 which may be secured in any modification wherein both the sheets and the desired manner to the supporting framewor cap strip are engaged by the securing clamp. or backing for holding the assembled sheets in proper position with relation thereto, if desired. A modified fastener, which is shown in Figure 5, may be employed for holding-thc sheeting to the framework as it is not essential that these fasteners be provided with more than two projections 8. For instance, the shank of the fasteners may be wrapped around one of the standards or cross pieces of the supporting framework or backing.

In the Figure 4 is shown a modified form of our invention wherein the portions 6 of the cap strip 4 extend down even with the portions 3 of the sheets and the clamps 7 engage both instead of only the portion 3 of the sheets, as shown in Figures 1, 2, 3 and 7. This extension of the portions 6 of the cap strip 4 imparts added strength to the joint.

In Figures 2 and 3, are shown constructions in which openings 10 are provided between the sheet and cap strip by suitably forming the material. The purpose of these openings is to prevent water from entering between the sheets by capillary attraction.

Figure 7 shows the manner of overlapping the ends of the sheets and cap strips. The sheets are merely overlapped and their edges nested. The cap strips are overlapped, the underneath portion of the upper and overlapping strip being cut away to avoid interference with the corresponding portion of the next lower cap strip. It is preferable to locate the lap in the cap strip so that it will not coincide with the lap in the sheets. A further method of overlapping the cap strips is to telescope the end of the lower strip into the adjacent end of the next upper strip, somewhat in the manner in which stovepipe is joined together.

From the description above, it will be clear that our invention provides a sheeting material which is well-adapted to all uses of metal sheeting and which, in addition, may be quickly applied with the aid of simple tools, such as a pair of pliers, to form a substantial structure which may be easily disassembled, if desired.

It will, furthermore, be apparent that we have provided a sheeting structure which can be manufactured from a sheet of irregular contour as, for instance, a trapezoidal form, without necessity for square shearing. For instance, if one edge of a sheet 18 out of parallelism with another edge of the sheet,

the sheet may, nevertheless, be completely flanged, inasmuch as this will merely result in one of the edge flanges (3 extending down a greater length at one end than at the other end.

It will, likewise, be apparent that the fastener which we utilize can be quickly and readily inserted between the sheeting from the inside. This fastener may be crimped or curved to any desired extent and this, in

itself, creates an adjustability between the lugs of the fastener or between such lugs and the framework of the building and thereby allows the fastener to accommodate itself to variations in the joint corrugations of the sheeting and the joint covering.

It has already been pointed out that the fastener may be ci'imped to such an extent that it will form indentations in thcextending legs of the corrugations With which it contacts so as to prevent displacement of the fastener in relation to the sheet and of the sheets in relation to each other. Such dis placements might be occasioned by vibrations under wind load or by slippage due to inherent weight of the sheeting, as when this sheeting is in vertical position. Furthermore, the fasteners are well-adapted to be located at overlapping joints to further ensure against leakage of wind or water. It may be desirable to initially crimp the fasteners to facilitate subsequent crimping after insertion in the sheeting structure.

Another point of considerable importance is that the sheeting structure is of such a form that it may be made from hot dipped galvanized sheeting without injury to the galvanized surfaces. It is well-known that these galvanized sheetings have a tendency to crack or scale off when bent around too small a radius. In addition, it will be noted that these joints of our structure which are bent at the most acute angle are protected from the weather, thus causing an additional safeguard against the elements.

Having thus described our invention, what we claim is:

1. A fastening means for the adjacent edges of sheeting comprising a shank and laterally extending wings, said shank being of such structure that when bent the fastening means will tighten upon and secure the sheeting.

2. A fastening means for the adjacent edges of sheeting comprising a flat shank with wings extending therefrom in the same plane with such shank, said shank being of such structure that it can be bent to secure the sheeting. 1

3. A fastening means for the adjacent edges of sheeting comprising a shank and spaced pairs of wings carried by said shank, said shank being of such structure that when bent the fastening means will tighten upon and secure the sheeting.

4. A fastening means for the adjacent edges of sheeting comprising a shank and spaced pairs of wings carried by said shank in the same lane with said shank, said shank being of such structure that it can be bent to secure the sheeting.

5. A fastening means for the adjacent edges of sheeting comprising a flat bendable shank, and spaced pairs of wings carried by said shank in the same plane with said shank, said shank being of such structure that when bent the fastening means will tighten upon and secure the sheeting.

6. A fastening means for adjacent ed es of sheeting comprising a cap strip, an a clamp including a shank and laterally extending wings, said shank being of such structure that when bent the fastening means will tighten upon and secure said cap strip and sheeting together.

7. A fastening means for adjacent edges of sheetin comprising a cap strip, and a clamp inc uding a shank and laterally extending wings, said shank being of such structure that vwhen bent the fastening means will tighten upon and secure said cap strip and sheeting together, and having por-,

tions securable to the frame work upon which the sheeting is mounted.

8. A clamp for fastening the adjacent edges of panels comprising a shank and a comparatively enlarged portion carried by,

said shank, said shank bein of such construction that when bent tie clamp will tighten upon the panels and render the clamp effective.

9. A fastening means for the adjacent edges of panels comprising a clamp including a shank andlaterally extending wings, said shank being of such a structure that when bent the fastening means will tighten upon and secure the panels.

In testimony whereof we hereby afiix our signatures.
